We are excited to release a new set of iGoogle themes today. Drawing on the arrival of summer and the spectacular beauty of the world around us, our new iGoogle themes focus on nature. To create these themes, we worked with organizations and photographers who capture the world's best nature photography, including National Geographic Society, BBC and Ansel Adams Gallery.

At its core, iGoogle is about personal expression. Themes are one of many ways we invite you to personalize your homepage with things that inspire you — artists, fashion designers, musicians, video games or simply the stunning beauty of the world around us.

Here's a quick preview of some of the highlights in our new nature collection:

National Geographic's "Ocean Blue" takes you from shark territory in the Caribbean to ice floes on the polar caps

The National Audubon Society's "Birds of Prey" features winged predators depicted in the classic Audobon hand-drawn illustration style

Art Wolfe's "Travels to the Edge" includes views deep into the forests of North America and aerial shots of river deltas and rice paddies
